"The urinary system, also known as the urinary tract or renal system, consists of the kidneys, ureters, bladder, and the urethra."
The study of the kidneys, bladder, and urethra, and their role in filtering and eliminating waste products from the body.
Kidneys: The kidneys are two bean-shaped organs located in the back of the abdomen. They act as filters for the blood, removing waste products and excess water to form urine.
Ureters: The ureters are long, thin tubes that carry urine from the kidneys to the bladder.
Bladder: The bladder is a muscular sac that stores urine until it is eliminated from the body.
Urethra: The urethra is a tube that carries urine from the bladder to the outside of the body.
Nephron: The nephron is the functional unit of the kidney, responsible for filtering the blood and producing urine.
Renal artery and vein: The renal artery carries blood to the kidneys, while the renal vein carries blood away from the kidneys.
Urinary tract infections: Urinary tract infections (UTIs) are infections in any part of the urinary system, including the kidneys, bladder, and urethra.
Prostate gland: The prostate gland is a male reproductive organ located near the bladder that can affect urinary system function.
Urinary incontinence: Urinary incontinence is the involuntary leakage of urine, which can be caused by various factors including weak pelvic muscles, nerve damage, and medications.
Urinary retention: Urinary retention is the inability to empty the bladder completely, which can be caused by various factors including prostate problems and nerve damage.
"The purpose of the urinary system is to eliminate waste from the body, regulate blood volume and blood pressure, control levels of electrolytes and metabolites, and regulate blood pH."
"The urinary tract is the body's drainage system for the eventual removal of urine."
"The kidneys have an extensive blood supply via the renal arteries which leave the kidneys via the renal vein."
"Each kidney consists of functional units called nephrons."
"The ureters are tubes made of smooth muscle fibers that propel urine towards the urinary bladder."
"Urine is stored in the urinary bladder."
"Urine is expelled from the body by urination (voiding)."
"The female and male urinary system are very similar, differing only in the length of the urethra."
"Urine is formed in the kidneys through filtration of blood."
"800–2,000 milliliters (mL) of urine are normally produced every day in a healthy human."
"This amount varies according to fluid intake and kidney function."
"The purpose of the urinary system is to... regulate blood volume."
"During urination, the urine is passed from the bladder through the urethra to the outside of the body."
"The purpose of the urinary system is to... regulate blood pressure."
"The kidneys have an extensive blood supply via the renal arteries which leave the kidneys via the renal vein."
"The purpose of the urinary system is to... control levels of electrolytes and metabolites."
"During urination, the urine is passed from the bladder through the urethra to the outside of the body."
"The urine is then passed through the ureters to the bladder, where it is stored."
"Urine is expelled from the body by urination (voiding)."
